The sound card provides stereo mix, if its drivers support that.
Go to the HP site and ensure you have the latest audio drivers for Windows 7 for your particular HP model.
If that does not expose Stereo Mix in Windows Sound when you show disabled devices, use the Windows WASAPI (loopback) choice in Audacity instead to record computer playback.
It is the standard practice that you should follow. There is nothing to compare. You should install HP’s latest Windows 7 audio driver for your computer model. Doing that will overwrite whatever drivers you have now, but you will still have an option in Windows Device Manager to roll back to the previous driver.
In that I now have stereo mix but it isn’t quite doing what I expected.
(Can I pause to say that’s the first time I’ve ever downloaded drivers and it was a total nightmare. The HP site not auto recognising, the program they wanted to download not initially downloading, and then not working, and then the new audio driver not initialling working properly. HP are a total nightmare! Thanks for the rant! Back to the business in hand!)
I’ve recorded using Audacity from Stereo mix on many computers before, and always been very pleased with the results. But this isn’t working as well. The quality isn’t as good. I’m not musically trained to be able to give an authoritative definition, but we variously describe it as ‘being slightly underwater’, tinny, and muffled. (It’s not a squeeling / whining sound, which is all a google search could suggest!)
Thanks for the help. Windows WASAPI (loopback) is a little better, but not the quality I normally expect from an Audacity recording. The original source is a stream, not something that can be downloaded.
